I am available at IRC channel #sfepy at Freenode (usually from 10 to 18 CE(S)T), so we can discuss there what requirements there are for a code to be included. 11 people on the list might look not so small, but me (and now Ondrej) are the only people actually writing the code, with one of my colleagues now starting too (even applying for a post-doc grant project). I see two principal areas that need to be addressed first: the documentation and the behaviour on failures/exceptions (the code works very well, but behaves as garbage-in/garbage-out and it is not easy for a casual user to recognize what in her/his input was wrong). No matter what the results of this discussion is, these must be done anyway, but every feedback is welcome! best regards, Robert --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
